Capturing all characters from a terminator's list

[Bobini1]

I've got the following bit of code:

struct TextTag
{
    static constexpr auto value = lexy::as_string<std::string> >> lexy::callback<std::string>(trimR);
    static constexpr auto rule = []{
        auto end =
          dsl::terminator(dsl::peek(dsl::eol));
        auto value = end.list(dsl::capture(dsl::unicode::character)); // this line is important
        return value;
    }();
};

It gets all characters in a line and then trims the result.
However, dsl::capture discards whitespace. I don't want that. dsl::identifier doesn't accept dsl::peek(dsl::eol) as the end condition so I can't use it either and I need to handle eof correctly. If I use neither of those and simply make a list of characters, nothing gets added to the sink.

I have spent like 5 hours on this already, is it really so hard to just get all characters in the sink literally?
